cowsay

Not intended to be used as a dagger module because it's so simple, more of an example to copy from.

Example .github/workflows/docker-publish.yaml:

``` name: 'build-and-push'

on: push: branches: - main

jobs: dagger: runs-on: ubuntu-latest permissions: contents: read packages: write steps: - name: Checkout uses: actions/checkout@v4

- name: Dagger Build & Push uses: dagger/dagger-for-github@v5 with: version: "0.11.0" verb: call args: build-and-push --registry=$DOCKER_REGISTRY --image-name=$DOCKER_IMAGE_NAME --username=$DOCKER_USERNAME --password=env:DOCKER_PASSWORD --build-context . env: DOCKER_REGISTRY: ghcr.io DOCKER_IMAGE_NAME: ${{ github.repository }} DOCKER_USERNAME: ${{ github.actor }} DOCKER_PASSWORD: ${{ secrets.GITHUB_TOKEN }} ```

This is how you acquire "packages" write permission, then call the dagger-for-github module with DOCKER_REGISTRY, DOCKER_IMAGE_NAME, DOCKER_USERNAME and DOCKER_PASSWORD set appropriately.

Nothing in the dagger module is specific to GHCR, it's just: * Build the container in the usual way with Dagger. Here we make a cowsay container that says "How now, brown cow", showing how to pass build context from the filesystem * Use `ctr.WithRegistryAuth(registry, username, password).Publish(ctx, registry+"/"+imageName)` to publish the container to the ghcr registry.
